Abstract
This study was conducted to observe the response of dogs' dental pulp to white mineral trioxide aggregate (MTA) when used as pulp capping material. The pulp of 15 dogs' teeth was experimentally exposed and capped with white MTA. The animals were sacrificed two months later and the specimens were prepared for histomorphological study. The pulp capped with white MTA showed a healing process with complete dentin bridge formation in all samples. In some cases, there was not a tubular dentin shape, but only a structure with an interesting morphological aspect sealing the exposure site. Only 2 specimens exhibited pulp inflammation. In conclusion, the data obtained in this study showed that white MTA has the necessary properties of a pulp capping material.
Highlights
A considerable number of articles about mineral trioxide aggregate (MTA) have been published in the dental literature
Deposition of neoformed hard tissue in direct contact with MTA was observed in cases of pulp capping and pulpotomy
Junn et al [15] has reported that pulp capped with MTA exhibited less inflammation and higher dentin bridge formation than the group treated with calcium hydroxide
Summary
A considerable number of articles about mineral trioxide aggregate (MTA) have been published in the dental literature. The data available about the use of MTA in conservative pulp treatment have shown good biological properties and results. Deposition of neoformed hard tissue in direct contact with MTA was observed in cases of pulp capping and pulpotomy. (13) capped monkey pulps and found mineralized tissue bridge in all specimens. Soares [14] observed that the mineralized bridge occurred in 96.43% of the specimens after pulpotomy with MTA. Junn et al [15] has reported that pulp capped with MTA exhibited less inflammation and higher dentin bridge formation than the group treated with calcium hydroxide. Faraco Junior and Holland [16] reported a healing process with complete tubular dentin bridge formation and no inflammation in any of the dog pulps capped with MTA
